Keying Security & Capacity

Keying Security
Keying Security is Equally Important to Physical Security in Commercial Security Applications
Keying security includes both (a) the security designed into the padlock's cylinder and operating key, and (b) the way in which the product is supplied to the marketplace. Master Lock stands alone among padlock suppliers in both categories of keying security:
- Master Lock provides the largest range of tight-tolerance cylinders and keys that vastly eliminate unwanted key interchange. This will better ensure that one employee's key will not be able to inadvertently open a second lock.
- Master Lock offers key control services, charted and reserved systems all of which assure that your company's padlocking system maintains the utmost in key integrity, even as you reorder padlocks year-after-year. This means that additional padlocks ordered can all be specified to operate by distinct keys, if that is your requirement.
Key System Capacity
All cylinders have limits to the number of change keys that can be provided. Be aware that whenever KD padlocks are supplied from open stock, the possibility exists that two or more locks provided will have the same operating key. This possibility of overlap increases as additional non-charted (see Charting Service) stock orders are received. It is important to know the key change limits of the padlocks you are considering for your security system. If the supplier does not, or can not, provide this information, the integrity of your keying system may be suspect.
Keying Options
-
-
Keyed Different (KD)
Each lock is opened by its own unique key that does not open any other lock in the set.
Keyed Different is the standard keying default on Master Lock and American Lock padlocks.
-
-
Keyed Alike (KA)
All padlocks in the set are opened by the same key. This option provides "same key" convenience and eliminates the need for multiple keys where numerous padlocks are used. KA in the product number (ie 3KA) designates that the products are Keyed Alike. In some cases the customer can select a key code for the KA locks
-
-
Master Keyed (MK)
In a Master Keyed system, a master key opens all the locks in the system although each lock also has its own unique key. This permits organizing master key systems along departmental or other functional lines to allow supervisory or emergency access.
MK in the product number designates that the products will be Master Keyed.
If the customer is adding on to an existing MK system, please specify the master key code.

-
Rekeyable Padlocks
The cylinder in rekeyable padlocks can be removed in order to (a) change the pinning or (b) replace the original cylinder with a new one, restoring security quickly and economically. This is ideal for situations where keys are lost or stolen. Products with this option can be identified by "rekeyable" in the item description. Rekeyable padlocks are available Keyed Different, Keyed Alike, or Master Keyed.
- Quickly restore security – should lost keys or employee turnover compromise your padlock system
- Save money – replace cylinders instead of locks
- Master Lock offers (8) rekeyable padlock cylinders
-
-
Interchangeable Core Locks
Interchangeable core padlocks and door locks don't require disassembly in order to change the cylinder. The figure-8 interchangeable cores (IC) can be removed and replaced with a single control key.
This convenience addresses common security issues:
- Preventing access when a key has been lost or stolen
- Resetting individual doors or gates with different locks to selectively limit access to authorized personnel
- Re-securing a building after temporary or contract employees end their term
- Securing a building against terminated employees
The Master Lock assortment of cylinders includes 16 distinct keyways to match existing profiles from Best®, Falcon®, and others. Cylinders, ProSeries® padlocks - Solid Steel, Solid Brass, Solid Aluminum, Weather Tough® and High Security Shrouded locks, with cylinders and mortise or rim cylinders for door applications are all available.
